Interesting that they didnt choose to have a bolean pin exit, and use an arbitrary -1, instead of false (didnt find)

For everyone who wants to do this in a simpler cleaner way try this: So you have a bunch of coins, items, etc in your level. Assign a unique ID (number etc) to each of them ( if they're too many you can do with automatically with an EditorUtilityWidget with a function that will add it). Then whenever you interact(collect) with each of these objects or whatever they are, get their ID number and Add it to an array in the SaveGame. Then whenever you load the level again, inside the level blueprint at begin play, if loading the level and not new game, just use the GetAllActorsByClass or Interface, and then check if their ID Contains in the SaveGame array , and if so -> DestroyActor. This will do the job. And easily so.

Thank

Sweet

So you literally have an array of structs which have actual object instances in them in your SaveGame? In blueprints. How? I don't get it, everywhere I looked they say you can't have objects in your SaveGame in blueprints. If someone has an insight or answer into this let me know.

I will try this tomorrow to make some random levels from a subset of tiles hopefully it works. These vids are lifesavers

Even years later, Your videos help massively, Thankyou!

You are a real Hero.

I enjow the videos but find it difficult to find te videos I am looking for. Can you please add links to related videos of a type inside your video descriptions etc. It would help alot

Best channel ever. By watching your videos, I’ve finished my game prototype two years ago. Thanks Mathew!

when player fly, ai not follow z axis why?

Can I use this node to smooth the rotation of an ai when it's nav between two points and it's changing direction?

Is it possible to scroll using an input other than mousewheel? I want the player to be able to scroll with their controllers.

you are the gote

question... if i have an object rotated as x0, y0, z -16.834499 ° .... what would the object orientation node return for that? I only ask because my material works fine when i use this for a spinning fan, but if i use this node for a packed level actor mesh... it rotates the wrong way because it no longer retains the model as its own seperate mesh with rotations and transforms. So i am trying to replace values with custom primitive data as a vector... but i have no idea the math of how it converts the editors rotation vlaues as an object orientation node.

Pysics material

thanks

thanks for simple method, getting class and using it, its cool

amazing explanation

just noticed last comment on this was 8 years ago, xD

no tum tum tum, tomatoes :( ?

brill tutorial thankyou Mathew! I'm planning to use a sphere to control location of the sphere mask however I'm trying to create a mask that blends one material to another using the BlendmaterialAttrivutes node in materials. I've noticed hardness doesn't work and I assume that's due to the way the blend works and it's either black or white only - what workaround would you suggest to be able to retain the full gradient within the alpha?

hey man, we miss you. There are SO many new nodes needing a clear description.

this just ended a 2 hour struggle with some code, thankyou!

What was the thing, that you could control how much a character is pushed away when it tries to step? im sure there's such a thing, but unreal sometimes likes to hide stuff really out of sight...

this is gold

Hey thanks from 5 year in the future check my new game I am making and this has just helped a ton. super simple and clearly explained, much appreciated!

Thank you.

but what is the difference between the normal fullscreenmode? or normal screenresolutions

So much for simple examples to explain complex topics.............and no delta explanation either

alternative for ue5 lumen ? non bake scene

I love these videos because whenever I have an idea I can just check out these very quickly instead of prototyping them myself because I'm too lazy :)

Hi Mathew WTF is attach actor to component node HTF do i use the bool value to call the attachment condition without actually using the execution of the attachment between the two as if i already called the ATC node in a macro and now just wanna know HTF to call thay event without attaching again

Your videos are so cool they never age out!

As I see they changed it and now u can scale from 0 to 100 for any resolution. If someone struggled with synching the resolution scale with screen percentage like me try to set screen percentage value to 0 or remove it's rules from config file completely. then it will adjust to match the resolution scale value (DLSS turned off).

how did the resize thing happen?

Thank you, super helpful

Wow thank you I was trying to figure this one out, Your video make it so clear. Thank you again.

I just used this today, thanks Mathew!

How did you make this though!? Can you do a tutorial on that?

1:57 So what if I don't have a player character? What if I need to do this with chess pieces? There's no generic Actor node that I can Get

Yea thanks. I was confused about asking if a Timer has been cleared and invalidated and looks like IsTimerActive is what I am looking for.

Quick tip because I was in this pickle🥒: In case anyone is checking to so if the trace hit anything with the 'Return Value' socket, be aware that it only returns true if the hit was BLOCKING not overlapped. This means it's not a great way to check to see if the hit was a success, I think a better check is more what Matt's doing here and check to see if the out hits array length is greater than 1.

Mathew you still there man ? 6 years into the future and this is such an amazing uncover ! Can we use this to extend the V-cam app to include camera pass through ? Cheers, b

Big question if you can help me with this... Assume that I'm in some sort of skill tree upgrade, and I can drag skills into my skill bar. I'm having a problem where, if I drag something, then exit the skill tree (Destroy it) and before dropping it, i still have the dragged skill. (it's still following the mouse) How would I fix that? PS: When exiting the tree, I get back to the "Set Input GAME ONLY" mode. (From player controller) Is there perhaps a way to FORCE DROP the widget? It's a very obscure problem, but i'm stuck with it...

You didnt explain what happens if your array has 10 items, and you resize it to 5

Are you in Unreal dev forum ? or where to find you ?

I still don't understand the purpose of "key". Annnnnd since UE5 now it has 70% to not print on screen, which is very very lame when you try to print on screen

If anybody happens to be watching this now, you also need "trace complex" turned on in the line trace or sphere trace node for it to work. Wish I figured it out sooner

Thank ya
